We demonstrate that a single-layer coating on a doped GaAs or Si substrate enables broadband antireflection and, R231 hence, broadband perfect absorption in the terahertz frequency range.This broadband behavior can be generally expected when the substrate material has a Drude-type dispersion.Our mathematical analyses show that the reflection from D

Abstract Parthenogenesis (PG) is a rare phenomenon occurring in humans, and understanding this may help us develop an explanation for such occurrences.Moreover, it may help reveal the cause of idiopathic ovarian teratoma (OT).We aim to explain the occurrence of PG and OT in humans based on a new hypothesis.Previous literature has been searched thro
